Frequently Asked Questions
What voltage and capacitance rating does EEEFC1H1R0R offer and how does its leakage current affect precision analog circuits?
EEEFC1H1R0R is a 1 µF aluminum electrolytic capacitor rated at 50 V with an extremely low leakage current of 0.003 mA. In precision analog timing or sample-and-hold circuits, such low leakage ensures the stored charge dissipates slowly, maintaining voltage accuracy over the hold interval and improving measurement precision compared to capacitors with higher leakage.
How does the 4 mm diameter, 5.4 mm height form factor of EEEFC1H1R0R compare to alternative capacitor types for compact PCB designs?
The 4 mm diameter by 5.4 mm height radial package of EEEFC1H1R0R occupies roughly 85 mm³ of PCB vertical space, which is significantly smaller than standard 6.3 mm or 8 mm diameter electrolytic capacitors at the same 1 µF capacitance. For 50 V applications where ceramic multilayer capacitors in 0402 or 0603 form factors are impractical due to voltage derating, EEEFC1H1R0R provides a compact wet aluminum alternative.
When would a designer select EEEFC1H1R0R over a film capacitor for a 50 V, 1 µF coupling stage?
EEEFC1H1R0R offers a 4 mm x 5.4 mm radial package that is considerably more compact than a typical 1 µF, 50 V polyester or polypropylene film capacitor, which often exceeds 12 mm in length and 6 mm in diameter. When PCB space is limited and cost is prioritized over the lower ESR and non-polarized advantage of film types, the aluminum wet electrolytic EEEFC1H1R0R is a practical choice for decoupling and coupling in low-frequency circuits below 10 kHz.
