UBY1H242MHL

The UBY1H242MHL is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can from Nichicon’s UBY series. It delivers 2400 µF capacitance at 50 V in a compact φ18 × 30.5 mm package with 7.5 mm lead spacing.

Designed for demanding power-electronic environments, this part offers high ripple-current capability, low ESR, extended high-temperature endurance and AEC-Q200 qualification for automotive applications such as control modules and engine-related systems.

Key Features

• Capacitance and Voltage — 2400 µF nominal capacitance at a 50 V rating with a tolerance of -20% to +20%.
• High ripple-current handling — Supports 2.265 A at 120 Hz (low frequency) and 3.02 A at 100 kHz (high frequency), enabling robust smoothing and decoupling in power stages.
• Low equivalent series resistance (ESR) — 25 mΩ measured at 100 kHz and 20°C, reducing losses and thermal rise under ripple load.
• High-temperature endurance — Specified lifetime of 3000 hours at elevated temperatures (up to 135°C) under rated conditions, suitable for high-temp operation.
• Leakage and dissipation — Leakage current specified as 3600 µA and tanδ (DF) of 0.12 at 20°C, 120 Hz, for predictable leakage and dissipation behavior.
• Robust packaging — Radial lead, can-style package (φ18 × 30.5 mm) with 7.5 mm lead spacing; available in bulk or bag packing for production use.
• Automotive-grade qualification — AEC-Q200 qualified and RoHS compliant, supporting use in automotive electronic systems.

Typical Applications

• Automobile control circuits — Suited for modules such as electric power steering and direct-injection engine drive where high ripple current and high-temperature tolerance are required.
• Engine control modules (ECUs) — Provides smoothing and decoupling in high-temperature power rails within engine electronics.
• Power stage filtering — Used for bulk smoothing and transient support in power converters and motor-drive electronics that demand low ESR and high ripple capability.

Unique Advantages

• High ripple capability: Numeric ripple ratings at 120 Hz and 100 kHz (2.265 A / 3.02 A) enable reliable suppression of AC components in harsh power environments.
• Low-loss operation: 25 mΩ ESR at 100 kHz minimizes I²R losses and heat generation under sustained ripple currents.
• Extended high-temperature life: Rated for 3000 hours at elevated temperatures (125–135°C range in the series), supporting long-term reliability in hot compartments.
• Automotive-grade assurance: AEC-Q200 qualification and RoHS compliance provide traceable suitability for vehicle electronics and regulatory conformity.
• Compact radial-can form factor: φ18 × 30.5 mm package with 7.5 mm lead spacing offers a balance of capacitance density and PCB-level serviceability.
• Production-ready availability: Mass-production status supports predictable sourcing for design-in and volume assembly.
