UWT1H221MNL1GS

The Nichicon UWT1H221MNL1GS is a chip-type aluminum electrolytic capacitor with a nominal capacitance of 220µF and a rated working voltage of 50V DC. It has a standard capacitance tolerance of ±20% (M). After 2 minutes of applying the rated voltage at 20°C, the maximum DC leakage current is 110µA (0.01CV). The maximum dissipation factor (tan δ) is 0.14 at 120Hz and 20°C.

As part of Nichicon's UWT 105°C chip-type aluminum electrolytic capacitor series, the UWT1H221MNL1GS operates over a temperature range of −55°C to +105°C. The series is rated for an endurance of 1,000 hours with the rated voltage applied at 105°C, after which it meets the specified endurance characteristics.

The UWT1H221MNL1GS has a rated ripple current of 220mArms at 120Hz and 105°C. The datasheet also provides ripple current frequency coefficients, including a coefficient of 1.50 at 10kHz or higher. This coefficient can be used to calculate the allowable ripple current at higher frequencies (e.g., 220 × 1.50 ≈ 330mArms); however, the datasheet does not explicitly specify 330mArms as a rated ripple current.

The UWT1H221MNL1GS is a chip-type aluminum electrolytic capacitor with a 10.0mm diameter × 10.0mm height (Ø10 × 10mm) package. According to the part numbering system, "NL" is the size code corresponding to this package size, while "M" denotes the ±20% capacitance tolerance. The package dimensions include a 10.3mm × 10.3mm plastic platform, and the UWT series is AEC-Q200 qualified.

The UWT series is designed for surface mounting on high-density PCBs and is suitable for automatic mounting machines using carrier tape. It is RoHS compliant. The datasheet specifies a resistance to soldering heat test of 250°C for 30 seconds and refers users to the Guidelines for Aluminum Electrolytic Capacitors for taping specifications, recommended reflow soldering conditions, land patterns, and minimum order quantities. The datasheet does not specify an MSL rating, reel quantity, REACH compliance, terminal plating, or a JEDEC reflow profile.
