Key Features

• Core Type Chip-type aluminum electrolytic capacitor with 1.8 mF capacitance and 25 V rated voltage.
• Temperature & Endurance Rated for −40°C to +135°C operation with a guaranteed lifetime of 2000 hours at 135°C.
• ESR and Low-temperature Specification Specified equivalent series resistance of 50 mΩ at 100 kHz, with added ESR specification confirmed after the −40°C test.
• Ripple Current Performance 600 mA at 120 Hz and 1.2 A at 10 kHz for applications requiring defined ripple handling.
• Reliability & Compliance AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and high-reliability designs.
• Package & Mounting Radial, can-style SMD (chip) package sized L: 1.65 × D: 1.6 cm, designed for automatic mounting machines fed with carrier tape; surface mount land size L: 1.63 × W: 1.63 cm.
• Capacitance Tolerance ±20% at 120 Hz, 20°C.

Typical Applications

• Automotive electronics AEC-Q200 qualification and −40°C to +135°C rating make this capacitor suitable for automotive electronic modules that require vetted components.
• High-temperature electronics Intended for systems and assemblies that must operate reliably at elevated ambient temperatures up to +135°C.
• Surface-mount production Designed for automated SMT lines—compatible with carrier-tape feeding and SMD placement for high-volume assembly.
• Power modules with defined ripple demands Use where measured ripple current capability (600 mA @120 Hz, 1.2 A @10 kHz) and a specified ESR (50 mΩ @100 kHz) are required.

Unique Advantages

• High-temperature endurance: 2000 hours specified at 135°C supports long-term operation in elevated-temperature environments.
• Qualified reliability: AEC-Q200 qualification and RoHS compliance provide traceable suitability for regulated and reliability-focused designs.
• Measured ESR after low-temperature test: ESR specification includes verification after −40°C testing, giving designers quantified low-temperature performance.
• Defined ripple-handling: Published ripple current ratings at 120 Hz and 10 kHz simplify thermal and performance budgeting in power designs.
• SMT-ready package: Radial can SMD format and carrier-tape compatibility reduce assembly friction for automated production.
