LGR2G101MELZ35

The LGR2G101MELZ35 is a snap‑in terminal aluminum electrolytic capacitor rated 100 µF at 400 V and specified for long life operation at elevated temperature. It is a polarized, radial can (snap‑in) package designed for general‑purpose power applications that require high voltage handling and extended endurance at up to 105°C.

Key value is long life assurance: the LGR series endures 10,000 hours of applied ripple current at 105°C and is RoHS compliant, making it suitable for designs that require sustained performance under thermal and electrical stress.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 400 V for high‑voltage energy storage and filtering tasks.
• Snap‑in Terminal, Radial Can — Snap‑in mounting for secure, vertical PCB attachment in power assemblies and chassis installations.
• High Temperature Long Life — Rated for operation to 105°C with a guaranteed lifetime of 10,000 hours at 105°C under rated ripple current.
• Operating Temperature Range — Specified from −25°C to +105°C for use in higher‑temperature operating environments.
• Capacitance Tolerance — ±20% at 120 Hz, 20°C for predictable performance in filter and energy‑storage circuits.
• Leakage Current Specification — Series-level leakage: I ≤ 3√(C·V) μA after 5 minutes application of rated voltage at 20°C, enabling predictable DC leakage behavior.
• Frequency‑Dependent Ripple Performance — Rated ripple: 690 mA at 120 Hz and 986.7 mA at 50 kHz; frequency coefficients provided for 400 V series to scale ripple capability across frequencies.
• Stability & Endurance Limits — After 10,000 hours at 105°C with DC bias plus rated ripple current the capacitor meets endurance criteria: capacitance change within ±25%, tan δ ≤ 250% of initial spec, and leakage current ≤ initial specified value.
• Physical Size — Body dimensions approximately L: 3.5 × D: 2.2 cm for layout and mechanical planning.
• RoHS Compliant — Conforms to RoHS requirements as stated for the LGR series.

Typical Applications

• Power Supply Bulk Filtering — Energy storage and smoothing in high‑voltage power supplies where 400 V rating and long life at 105°C are required.
• DC Link and Energy Buffering — Bulk capacitance for DC link stages or intermediate energy buffering in industrial power electronics.
• High‑Voltage Inverter and Converter Systems — Filtering and ripple handling in inverter/converter topologies that operate at elevated temperatures and require reliable long‑term performance.

Unique Advantages

• Long Life Endurance: Guaranteed 10,000 hours at 105°C under rated ripple current provides predictable aging behavior for maintenance planning.
• High Voltage Capability: 400 V rating supports higher‑voltage designs without the need for series stacking of lower‑voltage capacitors.
• Frequency‑aware Ripple Ratings: Published ripple current values at 120 Hz and 50 kHz plus frequency coefficients allow accurate ripple derating across application frequencies.
• Clear Reliability Limits: Endurance and shelf‑life performance criteria (capacitance, tan δ, leakage) are specified, enabling engineering tradeoffs and life‑cycle estimations.
• RoHS Compliance: Meets RoHS directive as noted for the series, supporting environmental and regulatory requirements.
