Frequently Asked Questions
What are the key electrical ratings of the ECA2AM100 and how do they determine suitable circuit applications?
The ECA2AM100 is rated at 10 µF capacitance with a 100 V voltage rating and ±20% tolerance. These parameters make it suitable for output filter capacitors in 48 V to 85 V DC power supplies, where 100 V provides a comfortable derating margin. The 0.01 mA maximum leakage current is low enough for precision timing and hold circuits that require minimal charge bleed-off during operation.
How does the 5 mm diameter radial package of ECA2AM100 affect PCB layout and footprint compatibility?
The ECA2AM100 has a 5 mm diameter cylindrical body with a standard 2 mm lead pitch, fitting into the same PCB footprint as many radial electrolytic capacitors in the 4.7 µF to 22 µF range at 100 V. This standard footprint allows designers to substitute or upgrade between capacitance values from 4.7 µF to 22 µF on a shared PCB layout, with maximum body heights typically ranging from 11 mm to 15 mm depending on capacitance variant.
Is the ECA2AM100 suitable for use in switch-mode power supply output stages, and what is the typical ripple current handling?
The ECA2AM100 M Series wet aluminum electrolytic capacitor is designed for general-purpose filtering in switch-mode power supplies operating up to 100 V DC. Panasonic M Series capacitors at 10 µF typically support ripple currents in the range of 40-70 mA at 100 kHz and 105°C, depending on case size. For high-ripple SMPS designs above 100 mA ripple, designers should consider paralleling multiple ECA2AM100 units or upgrading to Panasonic's FC or FM series with higher ripple current ratings.
What is the expected shelf life and operating life of the Panasonic ECA2AM100, and how should it be stored before assembly?
The ECA2AM100 carries a YTEOL rating of 6 years for supply availability, and Panasonic M Series aluminum electrolytics are typically rated for 1,000 to 2,000 hours of operating life at 85°C. For storage, the capacitor should be kept at temperatures between -25°C and 35°C with relative humidity below 75% to prevent electrolyte drying and oxide layer degradation. Units stored for more than 2 years should be voltage-conditioned by applying rated voltage through a 1 kΩ series resistor for 30 minutes before circuit installation.
