UBT1H330MPD8

The UBT1H330MPD8 is a radial-lead aluminum electrolytic capacitor offering 33 µF capacitance at a 50 V rating in a compact φ8 × 11.5 mm can. It is designed for high-temperature operation (–40 °C to +125 °C) and long endurance (2000 hours at 125 °C for this size/rating), targeting electronics that require durable, stable capacitance under sustained thermal and electrical stress.

Built to automotive-oriented reliability standards, the UBT1H330MPD8 combines AEC-Q200 qualification, low impedance and defined ripple-current capability to support power-rail decoupling and smoothing in demanding systems.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of −20% to +20%.
• High-temperature endurance — Rated operating range −40 °C to +125 °C with specified life of 2000 hours at +125 °C (condition applies to φ8, ≤50 V products).
• Low-loss electrical characteristics — Specified tan δ (DF) of 0.1 measured at 20 °C, 120 Hz, and an impedance of 450 mΩ for stable performance.
• Ripple-current capability — Supports 201 mA ripple at 120 Hz (low frequency) and 300 mA at 100 kHz (high frequency) for effective smoothing of power rails.
• Controlled leakage — Leakage current specified at 49.5 µA to limit standby drain and support predictable charging behavior.
• Compact radial package — φ8 can with 11.5 mm length, 3.5 mm lead spacing (±0.5 mm), and radial-lead mounting for through-hole assemblies; available in bulk/bag packing.
• Automotive-grade qualification — AEC‑Q200 rated and described in the UBT series datasheet as suited for automobile electronics requiring heavy-duty service.
• RoHS compliant — Meets RoHS environmental requirements.

Typical Applications

• Automotive electronics — Suited for automobile electronics and heavy‑duty services where stable capacitance at elevated temperatures is required.
• Power-rail smoothing — Provides ripple-current handling (201 mA at 120 Hz, 300 mA at 100 kHz) and low impedance for decoupling and filtering on 50 V rails.
• High-temperature embedded modules — Designed for modules operating up to +125 °C with defined endurance characteristics for sustained thermal stress.

Unique Advantages

• High-temperature durability: Rated for −40 °C to +125 °C operation with a specified 2000-hour life at +125 °C for this size and voltage, supporting prolonged use in thermally demanding environments.
• Automotive-focused qualification: AEC‑Q200 rating and series-level guidance for automobile electronics provide a pathway to meet vehicle-grade reliability needs.
• Predictable electrical performance: Defined tan δ, impedance and leakage specifications enable designers to model behavior in power-supply and decoupling circuits.
• Dual-frequency ripple support: Specified ripple ratings at both 120 Hz and 100 kHz allow designers to address low- and high-frequency noise components.
• Compact through-hole form factor: φ8 can with 3.5 mm lead spacing delivers a small footprint for radial-lead assemblies while maintaining useful capacitance and voltage rating.
• Regulatory and environmental compliance: RoHS compliance helps simplify integration into systems targeting restricted-substance requirements.
