UBX2G150MHL

The UBX2G150MHL is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon's UBX series. It is a radial lead, polarized can capacitor rated at 15 µF and 400 V, engineered for high‑temperature operation up to +150°C.

Designed for demanding automotive and high‑temperature electronic applications, the UBX2G150MHL delivers specified ripple handling, controlled dissipation factor and low leakage current in a compact φ12.5 × 25 mm package with 5 mm lead spacing.

Key Features

• Electrical Capacity & Voltage — 15 µF capacitance rated for 400 V DC, with capacitance tolerance of −20% to +20% at 20°C, 120 Hz.
• High‑Temperature Endurance — Designed for operation from −25°C to +150°C with a rated endurance of 1000 hours at 150°C.
• Ripple Current Performance — Low‑frequency ripple current of 105 mA (120 Hz) and high‑frequency ripple current of 189 mA (100 kHz) to support power conditioning needs.
• Leakage and Dissipation — Leakage current specified at 340 µA and a tangent of loss angle (tanδ) of 0.24 measured at 20°C, 120 Hz for the 350–400 V rating.
• Package & Mounting — Radial lead, can-style package with nominal dimensions φ12.5 × 25 mm (L: 2.5 cm × D: 1.25 cm) and 5.0 mm lead spacing (±0.5 mm tolerance).
• Reliability & Qualification — High‑reliability UBX series construction with AEC‑Q200 listed in product specifications.
• Compliance & Availability — RoHS compliant and available in mass production; packaging options include bulk (no terminal forming) or bag packing.

Typical Applications

• Automotive electronics — Suited for automobile electronics where high temperature endurance and robust voltage rating are required.
• On‑board power conditioning — Filtering and decoupling in high‑temperature power supply circuits that require reliable ripple handling at up to 400 V.
• Harsh‑environment electronics — Use in electronic modules exposed to elevated ambient temperatures up to +150°C and prolonged duty cycles.

Unique Advantages

• High‑temperature capability: Rated to +150°C with 1000 hours endurance at that temperature for reliable operation in hot environments.
• High voltage handling: 400 V rating supports high‑voltage DC buses without upsizing the capacitor footprint.
• Compact, serviceable form factor: φ12.5 × 25 mm radial can with 5 mm lead spacing provides a small footprint for space‑constrained boards.
• Measured electrical stability: Specified tanδ (0.24) and leakage current (340 µA) at measurement conditions give predictable losses and standby characteristics.
• Designed for automotive grade use: AEC‑Q200 listed in specifications and described as suitable for automobile electronics in the series documentation.
• Production readiness: Mass production status and standard packaging options simplify sourcing and assembly planning.
