UAQ2D101MHD

The UAQ2D101MHD from Nichicon is a radial-lead aluminum electrolytic capacitor offering 100 μF capacitance at a 200 V rating. It is built in a φ12.5 × 35.5 mm can with 5 mm lead spacing and is supplied in bulk/bag packaging.

Designed for general-purpose electronics, the UAQ2D101MHD combines a wide operating temperature range (−40°C to +105°C), robust ripple-current capability, and built-in safety features to address assemblies that require high-voltage electrolytic capacitance with defined lifetime characteristics.

Key Features

• Capacitance & Voltage — 100 μF nominal capacitance with ±20% tolerance at a 200 V rated voltage.
• High Ripple-Current Capability — Rated ripple current of 335 mA at 120 Hz (low frequency) and 536 mA at 10 kHz (high frequency), with frequency coefficients defined in the series data.
• Wide Temperature Range & Endurance — Operates from −40°C to +105°C and meets endurance specifications after 2000 hours at 105°C under rated bias and ripple conditions.
• Low Leakage — Specified leakage current of 900 μA.
• Safety Design — Series-level safety features include improved protection for abnormal over-voltage and a pressure relief vent designed to operate without dangerous conditions.
• Radial Can Packaging — Radial lead can package (φ12.5 mm diameter, 35.5 mm length) with 5.0 mm lead spacing for through-hole assemblies.
• RoHS Compliance — Compliant with RoHS directive requirements.

Typical Applications

• General-purpose electronics — Provides 200 V, 100 μF bulk capacitance for circuits specifying general-purpose electrolytic capacitors.
• High-temperature environments — Rated to −40°C to +105°C with 2000 hours endurance at 105°C for applications that require defined high-temperature lifetime performance.
• High ripple-current circuits — Suitable where elevated ripple-handling is needed, given the specified ripple current at both low and high frequencies.

Unique Advantages

• Clear, verifiable specifications — Published values for capacitance, tolerance, leakage, ripple current, and lifetime make it straightforward to validate against design requirements.
• Built-in safety considerations — Improved abnormal-voltage tolerance and a pressure relief mechanism enhance safety in the event of excessive stress.
• Through-hole mounting simplicity — Radial lead can and 5 mm lead spacing simplify PCB layout and assembly for through-hole designs.
• RoHS-compliant manufacturing — Meets environmental compliance expectations for restricted substances.
• Documented frequency ripple behavior — Series-level frequency coefficients for ripple current allow designers to estimate performance across 50 Hz to 10 kHz and above.
