Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 80 V and capacitance tolerance of ±20% (−20% to +20%).
• High‑Temperature Endurance — Rated for operation from −40 °C to +125 °C with an endurance specification of 3500 hours at 125 °C.
• Low‑Temperature ESR Specification — ESR characterized down to −40 °C to support performance in cold starts and low‑temperature conditions.
• Ripple Current Performance — Low frequency ripple current of 550 mA (120 Hz) and high frequency ripple capability of 1.1 A (10 kHz), enabling robust filtering in power circuits.
• Measured ESR — Equivalent series resistance of 170 mΩ measured at 20 °C, 100 kHz.
• Leakage & Dissipation — Specified leakage current of 264 µA and tan δ (DF) of 0.12 measured at 20 °C, 120 Hz (80 V rating).
• Surface‑Mount Packaging — Chip‑type can (φ18 × 16.5L) in embossed carrier taping for automatic mounting machines.
• Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified for applications requiring recognized reliability standards.

Typical Applications

• Automotive electronic modules — Suited for automotive systems that require high‑voltage capacitance and operation to +125 °C, backed by AEC‑Q200 qualification.
• High‑temperature power electronics — Provides bulk energy storage and ripple handling in boards exposed to elevated ambient temperatures.
• Automated surface‑mount assembly — Embossed carrier taping makes the part compatible with pick‑and‑place and reflow production flows.
• Industrial equipment — Applicable where stable capacitance, defined ESR, and long endurance at high temperature are needed.

Unique Advantages

• High voltage capability: 80 V rating with 330 µF capacitance supports higher DC bus and power rail applications without paralleling multiple parts.
• Wide temperature range: −40 °C to +125 °C operation ensures usable performance across harsh environmental conditions.
• Long endurance at elevated temperature: 3500 hours at 125 °C offers predictable life for designs that operate continuously at high temperature.
• Defined ESR and ripple handling: 170 mΩ ESR (100 kHz) and up to 1.1 A ripple at 10 kHz reduce voltage ripple and heating in power circuits.
• Production‑friendly packaging: Embossed carrier tape supports automated placement for highvolume manufacturing.
• Industry qualification and RoHS compliance: AEC‑Q200 qualification and RoHS compliance support regulated and quality‑focused design requirements.
