47uf 35V Surface Mount Electrolytic Capacitor (Reel of 1000)
The 47uf 35V Surface Mount Electrolytic Capacitor is a high-reliability polarized capacitor designed for compact PCB layouts in modern electronics, offering 47 microfarads of capacitance at a 35-volt DC working voltage. Electronics engineers, PCB designers, and manufacturing professionals rely on this component for power supply filtering, signal coupling, and energy storage applications in space-constrained designs. This capacitor solves the critical challenge of maintaining stable voltage rails and reducing ripple noise in switching power supplies, audio amplifiers, and industrial control circuits where board real estate is premium.
Product Overview
Surface mount electrolytic capacitors operate on the principle of storing electrical charge across a polarized aluminum oxide dielectric layer. The 47uf 35V variant utilizes a specially formulated electrolyte and precision-engineered cathode structure to deliver low equivalent series resistance (ESR) and extended operational life. The 35-volt rating provides a safety margin for typical 24V and 28V industrial applications, while the 47-microfarad value makes it ideal for intermediate filtering stages where bulk capacitance is required without excessive component footprint. The reel format containing 1000 units ensures consistent supply for high-volume manufacturing, prototyping labs, and contract electronics assembly operations.
This surface mount package design eliminates the need for through-hole drilling, reducing assembly time and improving PCB density. The capacitor features excellent frequency response characteristics, maintaining stable capacitance across the operating temperature range of -40 to +85 degrees Celsius. The low-profile form factor integrates seamlessly into modern SMD reflow soldering processes, with lead-free solder compatibility ensuring RoHS compliance. The 1000-unit reel comes on standard tape and reel packaging, compatible with automated pick-and-place equipment used in manufacturing facilities across India and globally.

How to Use
When integrating the 47uf 35V surface mount electrolytic capacitor into your PCB design, ensure proper polarity orientation with the positive terminal connected to the higher potential node and the negative terminal to ground or lower potential. The capacitor must be soldered using standard SMD reflow processes with peak reflow temperatures not exceeding 260 degrees Celsius for 10 seconds maximum, as per IPC-A-610 standards. Place the component as close as possible to the power supply output or the IC requiring filtering to minimize parasitic inductance and maximize high-frequency noise attenuation. Verify that your PCB layout includes adequate copper pour around the capacitor pads to ensure low-impedance return paths and optimal thermal dissipation during operation.
For applications involving ripple current or thermal stress, calculate the actual ripple current flowing through the capacitor and verify it remains below the component's rated ripple current specification to prevent premature failure. In high-temperature environments exceeding 70 degrees Celsius, derate the capacitor's voltage rating by approximately 10 percent for every 10-degree Celsius increase above the standard 20-degree Celsius reference. When using the tape and reel format, store components in a dry environment with relative humidity below 60 percent and temperature between 15-25 degrees Celsius to maintain electrolyte integrity. Inspect components visually before assembly for any signs of leakage, corrosion, or mechanical damage that could indicate manufacturing defects or improper storage conditions.
Frequently Asked Questions
What is the difference between electrolytic and ceramic capacitors for power supply applications?
Electrolytic capacitors like the 47uf 35V variant offer significantly higher capacitance values in compact packages, making them ideal for bulk energy storage and low-frequency filtering in power supplies. Ceramic capacitors excel at high-frequency noise suppression due to lower ESR but provide much smaller capacitance values. In modern power supply designs, both are used together: electrolytic capacitors handle bulk filtering and energy buffering, while ceramic capacitors suppress high-frequency switching noise. The 47uf value is optimal for intermediate filtering stages where you need substantial capacitance without excessive board space consumption.
Can I use a 47uf 35V capacitor in a 24V application?
Yes, absolutely. The 35V voltage rating provides a safety margin above your 24V operating voltage, which is a fundamental design principle in electronics. Using a component rated for 35V in a 24V circuit ensures reliable operation with headroom for transient voltage spikes that commonly occur in industrial and automotive environments. Never use a capacitor rated below your circuit's maximum voltage, as this causes premature failure and potential catastrophic circuit damage. The 35V rating in this case is ideal for 24V and 28V systems commonly found in industrial control, automotive, and telecommunications applications.
What does ESR mean and why is it important for my application?
Equivalent Series Resistance (ESR) is the internal resistance of the capacitor measured at 100kHz, typically ranging from 0.5 to 1.2 ohms for this 47uf 35V component. Low ESR is critical because it directly impacts ripple voltage on your power rails: higher ESR causes greater voltage ripple and increased heat dissipation. In switching power supplies operating at 50-500kHz, low ESR capacitors minimize output voltage ripple, improve transient response, and reduce thermal stress. For audio applications, low ESR ensures clean power delivery to amplifier circuits, reducing noise and distortion. Always verify ESR specifications when selecting capacitors for noise-sensitive or high-frequency applications.
How do I identify the polarity of a surface mount electrolytic capacitor?
Surface mount electrolytic capacitors have polarity markings printed on the component body, typically a stripe or marking on the negative terminal side. Before installation, verify the marking against your PCB silkscreen diagram and schematic. The positive terminal must connect to higher potential, and the negative terminal to ground or lower potential. Installing with reversed polarity causes immediate failure, component heating, and potential circuit damage. Always double-check polarity during PCB layout and before reflow soldering. If you receive components on tape and reel, the tape orientation also indicates polarity according to IEC 60617 standards.
What is the shelf life of surface mount electrolytic capacitors?
Surface mount electrolytic capacitors have a typical shelf life of 2-3 years when stored in dry conditions at 15-25 degrees Celsius with relative humidity below 60 percent. The electrolyte gradually evaporates over time, causing capacitance drift and ESR increase. For components stored longer than 12 months, perform a visual inspection and consider running a capacitance measurement before critical assembly. The Engineer Store sources components with recent manufacturing dates to ensure maximum shelf life. Proper storage in original tape and reel packaging with desiccant packs significantly extends usable life and maintains component specifications.
