ECA-1HMR47 Aluminum Electrolytic Capacitor For Small-Signal Filtering

Some analog and control circuits still call for a small polarized electrolytic for coupling, bias filtering, or time-constant work. ECA-1HMR47 is useful in audio paths, reference filtering, and slow feedback loops where capacitance needs are under 1 µF but voltage margin matters. Place it where leakage and polarity are controlled, and keep the node impedance in mind for best stability. ECA-1HMR47 is a radial, polarized aluminum electrolytic capacitor rated at 0.47 µF and 50 V, with 2000 hours endurance at 85°C. Through-hole mounting makes it easy to service and replace in long-life equipment. If you need cleaner high-frequency behavior, add a small ceramic in parallel. Request a quote for ECA-1HMR47.
