Key Features
- 100µF capacitance at 63V rating delivers substantial energy storage for bulk filtering in power supply output stages
- 8mm diameter radial leaded through-hole package fits standard PCB hole patterns for high-volume wave-soldering assembly
- Wet aluminum electrolytic construction provides high capacitance density per unit volume compared to ceramic or film capacitors at equivalent voltage ratings
- Very low leakage current of 0.063mA minimizes idle power drain in battery-backed and standby power supply designs
- RoHS and REACH-compliant Pb-free construction meets global environmental regulations for consumer and industrial products
Applications
The ECA1JM101 is commonly used as a bulk output filter capacitor in AC-DC power supplies, DC-DC converters, and linear regulator output stages where 100µF at 63V provides effective low-frequency ripple attenuation. It serves in motor-drive input bulk capacitor banks, audio amplifier power rails, and industrial control panel bypass networks where the large capacitance value smooths transient current demands from load steps. The radial through-hole package suits prototyping, repair, and cost-sensitive production designs using wave soldering or hand assembly.

Frequently Asked Questions
What is the capacitance and voltage rating of the ECA1JM101, and which power supply rail voltages does it support?
The ECA1JM101 is rated at 100µF and 63V DC working voltage, making it suitable for filtering on 12V, 24V, 48V, and 56V rails with adequate derating margin; at 63V maximum, it can serve as the bulk output capacitor in 48V telecom converters or 24V industrial supply outputs without exceeding voltage limits.
How does the 0.063mA leakage current of the ECA1JM101 affect long-term battery drain in a standby power circuit?
At 0.063mA (63µA) leakage current, the ECA1JM101 consumes roughly 1.5mW from a 24V standby rail; over 8760 hours (one year), this equates to about 13mAh of charge from a backup battery, which is negligible for most UPS or RTC backup designs using 1000mAh lithium cells but worth accounting for in multi-capacitor arrays with dozens of units.
What is the body diameter and lead spacing of the ECA1JM101, and which standard PCB footprint does it use?
The ECA1JM101 has an 8mm body diameter and uses the standard 3.5mm radial lead pitch common to most 8mm aluminum electrolytic capacitors, fitting IPC-compliant through-hole footprints for 8mm diameter radial parts; the capacitor is installed with leads bent to 3.5mm spacing and seated flat or standing vertical depending on the available board height.
When is the ECA1JM101 preferable to a multilayer ceramic capacitor (MLCC) at 100µF for a 12V DC-DC converter output?
At 100µF and 63V, ceramic X5R or X7R MLCCs of equivalent value would typically require multiple 50V-rated 0805 or 1210 packages at significantly higher cost per µF; the ECA1JM101 electrolytic delivers 100µF in a single 8mm through-hole part at lower BOM cost, though the MLCC array would have lower equivalent series resistance (ESR) and longer service life at elevated temperatures above 85°C.
How should the ECA1JM101 be derated when used in circuits with ripple current from a switching converter at 100 kHz?
Wet aluminum electrolytic capacitors like the ECA1JM101 have an ESR that rises at high frequency; at 100 kHz the ripple current heating in the 100µF body must be checked against the datasheet ripple current rating (typically 120–300mA for 8mm diameter parts) and derated to 80% of rated ripple at 85°C ambient, or the capacitor should be replaced by a low-ESR type if the converter switching frequency exceeds 50 kHz continuously.
