KELTRON 0.47uF 63V Radial Electrolytic Capacitor

Description

The Keltron 0.47uF 63V Radial Electrolytic Capacitor is a high-reliability, through-hole electronic component designed for precise signal filtering, audio coupling, and high-frequency decoupling applications. Manufactured by Keltron, this miniature polar component features a robust 63V rating, making it highly versatile for both low-voltage logic control lines and standard industrial power rail configurations.

Due to its lower capacitance value of 0.47uF, this aluminium electrolytic capacitor is ideal for fine-tuning timing constants, blocking DC biases in small signal paths, and removing low-frequency noise from sensitive sensor inputs. Its radial lead design ensures a minimal physical footprint on your printed circuit board (PCB), allowing for tight component density in compact enclosures.

Applications

• Audio Circuitry: Acting as an input/output coupling capacitor to block DC offsets while allowing AC audio signals to pass cleanly between amplifier stages.
• Signal Filtering: Creating high-pass or low-pass filters to clean up low-current sensor lines and signal communication buses.
• Timing Circuits: Working alongside resistors in basic RC timing networks to establish specific oscillator intervals or delay states.
• Decoupling/Bypassing: Suppressing voltage ripples in low-power amplifier bias circuits.

Usage Notes

• Polarity Sensitivity: This is a polarized component. Ensure the longer lead (Positive) and the striped side of the sleeve (Negative) are correctly aligned with your schematic layout before soldering to prevent component failure.
• Voltage Derating: For maximum longevity and reliability in continuous operating conditions, it is best practice to run the component below 80% of its rated voltage (50V DC or lower).

Frequently Asked Questions (FAQ)

Q: How can I visually identify the positive and negative terminals on this capacitor?
A: The negative terminal is clearly marked by a distinct vertical stripe on the body sleeve containing minus (-) symbols. Additionally, the positive lead is physically longer than the negative lead on an uncut factory unit.

Q: Can I use this capacitor in an AC mains circuit?
A: No. This is a polarized DC electrolytic capacitor. Exposing it to continuous AC alternating current or reverse voltage can cause internal pressure buildup, venting, or absolute component failure.

Q: Can I use this in place of a 0.47uF ceramic or film capacitor?
A: You can use it if the circuit operates strictly with DC voltages and respects the polarity. However, keep in mind that electrolytic capacitors have higher equivalent series resistance (ESR) and leakage current compared to ceramic or film options, which may affect precision RF or timing loops.
