How BHC Capacitors ALS31A472NF400 from KEMET Improve Power Supply Stability

When it comes to ensuring the stability of power supplies in electronic devices, capacitors play a crucial role. The BHC series capacitor ALS31A472NF400 by KEMET is an excellent choice for enhancing performance in various applications. This capacitor has a capacitance of 47μF and a voltage rating of 400VDC, making it suitable for high-voltage filtering and smoothing circuits.\u00a0KEMET’s BHC series uses aluminum electrolytic technology with non-solid manganese dioxide as the cathode material. This design ensures low ESR (Equivalent Series Resistance) values which are critical for efficient power delivery. According to KEMET’s datasheet, the ESR value at 120Hz can be as low as 0.15Ω, contributing significantly to reducing heat generation under heavy load conditions.”One practical example where this capacitor shines is in LED lighting systems. In these setups, maintaining constant current through LEDs requires stable DC voltage levels after rectification. By incorporating ALS31A472NF400 into the circuit design, engineers can achieve better ripple suppression and longer operational life due to its robust construction and high ripple current capability – up to 1.2A RMS at 100Hz ambient temperature of 85°C.\
