Frequently Asked Questions
What makes the ECA1HM2R2 suitable for precision analog circuits compared to higher-capacitance electrolytics?
The ECA1HM2R2 offers a low 2.2 µF capacitance at 50 V with an ultra-low leakage current of just 0.003 mA, which is critical in precision analog bias networks and sensor interfaces where excessive leakage would introduce offset errors and degrade measurement accuracy beyond acceptable limits.
For a 48 V industrial sensor power supply, can ECA1HM2R2 safely serve as the output bypass capacitor?
Yes. With a 50 V voltage rating, the ECA1HM2R2 provides a comfortable 2 V headroom above a 48 V rail. Its 2.2 µF capacitance provides effective high-frequency noise bypass at frequencies above 1 kHz, and its 5 mm diameter radial form factor fits standard through-hole PCB pads used in industrial sensor modules.
How does the 5 mm body diameter of ECA1HM2R2 compare to larger radial capacitors in PCB layout planning?
The ECA1HM2R2's 5 mm diameter body occupies significantly less board area than 8 mm or 10 mm radial capacitors, allowing tighter component placement in multi-stage filter networks. It uses a standard radial lead pitch compatible with 2 mm or 2.5 mm pad spacing commonly specified in industrial and consumer PCB designs.
When evaluating M Series Panasonic capacitors, what lead time should procurement teams plan for ECA1HM2R2?
The factory lead time for ECA1HM2R2 is approximately 17 weeks and 2 days from Panasonic, so procurement teams managing programs with 2.2 µF / 50 V radial capacitor requirements should place orders at least 5 months ahead of scheduled PCB assembly start dates to avoid production delays.
