Frequently Asked Questions
What capacitance and leakage current does the ECA2EM2R2 offer for power supply decoupling?
The ECA2EM2R2 provides 2.2µF capacitance with a leakage current of only 0.043mA, making it well-suited for power supply decoupling and filtering applications. This low leakage supports stable DC bias conditions in circuits operating at voltages from 5V to 25V, minimizing quiescent power loss in battery-powered and mains-powered designs alike.
How does the 6.3mm radial diameter of the ECA2EM2R2 influence PCB layout decisions versus SMT alternatives?
The 6.3mm radial leaded package of the ECA2EM2R2 requires through-hole placement, occupying a 6.3mm hole diameter footprint on the PCB. While larger than SMT equivalents, it offers easier manual rework, better mechanical hold in vibration-prone environments, and typically higher ripple current handling than equivalent-value SMT polymer capacitors of 2.2µF rated below 50V.
In which audio or power circuit applications does a 2.2µF aluminum electrolytic capacitor provide optimal filtering performance?
A 2.2µF aluminum electrolytic like the ECA2EM2R2 provides effective filtering at frequencies below approximately 30kHz, making it ideal for output smoothing on linear voltage regulators, audio coupling between amplifier stages at 20Hz to 20kHz bandwidth, and bulk decoupling on motor driver power rails carrying several hundred milliamps of ripple current.
What is the factory lead time for the ECA2EM2R2 and what procurement steps should buyers take to ensure availability?
The ECA2EM2R2 has a factory lead time of 21 weeks. Buyers should place orders at least 6 months ahead of production start dates and maintain a safety stock buffer of 2 to 3 months for ongoing production runs. For urgent needs, checking distributor stock worldwide and considering cross-referenced 2.2µF aluminum electrolytic capacitors from alternative manufacturers can help bridge supply gaps.
