Frequently Asked Questions
What capacitance, voltage, and case size does the EEE-HA1E100WR provide for automotive ECU designs?
The EEE-HA1E100WR provides 10 µF capacitance at a 25 V rating with ±20% tolerance in a 4 mm diameter by 5.4 mm tall SMD case. This compact footprint fits in dense automotive PCBs near microcontrollers and regulators where 10 µF decoupling capacitors are needed to suppress power rail transients on 12 V automotive supplies.
How does the 1000-hour lifetime at 105°C affect design choices for the EEE-HA1E100WR in passenger vehicle applications?
A 1000-hour endurance at 105°C is the baseline for AEC-Q200 automotive capacitors. In practice, most automotive ECU ambient temperatures remain below 85°C during normal operation, which doubles expected lifetime to approximately 2000 hours or more based on the Arrhenius model. Designers specify this part knowing real-world temperatures stay within a 40°C to 85°C range for most vehicle locations.
What is the ripple current limit of the EEE-HA1E100WR and where is it a bottleneck?
The rated ripple current is 22 mA, which limits use as a standalone output filter for switching regulators operating above 500 kHz with output currents exceeding a few hundred milliamps. For higher ripple current requirements, multiple EEE-HA1E100WR units can be paralleled, or a combination of 10 µF aluminum electrolytic and 1 µF ceramic capacitors is used to divide ripple across complementary technologies.
Is the EEE-HA1E100WR a direct drop-in replacement for standard non-automotive 10 µF 25 V SMD capacitors?
The EEE-HA1E100WR shares the same 4 mm x 5.4 mm footprint and 10 µF 25 V specification as many standard industrial SMD aluminum electrolytics, making it a physical drop-in replacement. The main differences are the AEC-Q200 qualification level and the 105°C rated temperature, both of which exceed typical commercial-grade parts rated at only 85°C, so automotive-qualified parts can replace commercial ones without derating concerns.
