Applications
The EEE-HD1C470AP is used in automotive electronic control units (ECUs), infotainment systems, and advanced driver assistance system (ADAS) modules where a long-life, high-temperature SMD electrolytic capacitor is needed for bulk energy storage and ripple current filtering. Its 5000-hour rating at 105°C meets the durability demands of under-hood and cabin electronics subjected to wide ambient temperature cycling. It is also suitable for industrial power supply output filtering, DC-DC converter bulk capacitance, and motor controller EMC suppression in demanding thermal environments.

Frequently Asked Questions
What are the key electrical ratings of the EEE-HD1C470AP, and what power supply filtering role does it serve?
The EEE-HD1C470AP is rated at 47 µF capacitance and 16 V maximum working voltage, with a ±20% capacitance tolerance and 70 mA ripple current capability. These specifications make it well suited for output bulk capacitance in 5 V to 12 V switching power supplies, low-dropout regulator smoothing, and EMI filtering in automotive and industrial electronic systems.
What lifetime and temperature rating does the EEE-HD1C470AP carry, and why does this matter for automotive applications?
The EEE-HD1C470AP is rated for 5000 hours at 105°C, a standard automotive-grade endurance benchmark. In ECU, body control module, and powertrain controller designs, capacitors must survive years of thermal cycling between -40°C and over 85°C ambient — the 105°C, 5000-hour rating ensures the component outlasts the intended vehicle service life without capacitance degradation or electrolyte dry-out.
How does the 6.3 mm x 5.8 mm SMD footprint of the EEE-HD1C470AP influence PCB layout in compact automotive modules?
The 6.3 mm diameter and 5.8 mm height SMD case of the EEE-HD1C470AP allows placement on densely populated PCBs typical in automotive ECUs and ADAS modules, where through-hole capacitors would consume more vertical clearance. The SMT form factor supports automated reflow assembly and enables closer component spacing compared to radial through-hole equivalents with the same 47 µF, 16 V rating.
When should the EEE-HD1C470AP be chosen over a ceramic MLCC for bulk capacitance in automotive designs?
Aluminum electrolytic capacitors like the EEE-HD1C470AP are preferred over ceramic MLCCs when high capacitance values of 47 µF at 16 V are needed at lower cost and smaller physical size than an equivalent MLCC stack. MLCCs also suffer significant capacitance loss at DC bias (derating), whereas electrolytics maintain their rated capacitance more predictably under voltage, making the EEE-HD1C470AP more suitable for bulk energy storage in automotive power rails.
