The United Chemi-Con ESMR421VSN561MR45S is a downsized aluminum electrolytic capacitor belonging to the SMR series. Designed for operation in a temperature range of -25°C to +85°C, this capacitor features a rated voltage range from 400 Vdc to 450 Vdc.
Key electrical specifications include a capacitance tolerance of ±20% at 120Hz and 20°C, and a maximum leakage current of 3 µA (formula: I = 3 * C * V). The dissipation factor (tanδ) is a maximum of 0.15 for 400V and 0.20 for 420 & 450V at 120Hz and 20°C. It also exhibits good low-temperature characteristics, with the impedance ratio Z(-25°C)/Z(+20°C) at 120Hz being a maximum of 8.
This capacitor is built for reliability, offering an endurance of 2,000 hours at 85°C with rated ripple current applied. It also has a shelf life of 1,000 hours at 85°C without voltage. The SMR series is noted for being downsized with high ripple current capabilities compared to the SMQ series, and it is a non-solvent resistant type.
The ESMR421VSN561MR45S is a snap-in type capacitor, suitable for through-hole mounting. Terminal codes VS (for diameters φ22 to φ35) and LI (for diameter φ35) are available.
