LGN2V151MELZ30

The LGN2V151MELZ30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGN series, designed for general‑purpose power applications that require a 350 V rated voltage and 150 µF capacitance. It offers a compact radial can snap‑in package with high‑temperature endurance and defined ripple performance for reliable use in demanding thermal environments.

This part is optimized for designs requiring long‑term operation at elevated temperature: it withstands 3000 hours of rated ripple current at 105°C and is compliant with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Rated Capacitance & Voltage — 150 µF at 350 V, suitable for circuits needing a mid‑range capacitance with high DC voltage capability.
• High‑Temperature Endurance — Specified operating temperature range of −25°C to +105°C with a guaranteed 3000 hours endurance at 105°C under rated ripple conditions.
• Snap‑In Radial Can Package — Snap‑in mounting simplifies secure installation on power PCBs and chassis assemblies.
• Compact Dimensions — Size L: 3 × D: 2.2 cm with a maximum seated height of 1.181 inch, offering a smaller case option (one rank smaller than LGU) for tighter layouts.
• Ripple Current Ratings — Rated ripple current of 820 mA at 120 Hz and 1.173 A at 100 kHz to support AC ripple handling in DC bias conditions.
• Electrical Stability — Capacitance tolerance ±20%; leakage current meets I ≤ 3/√C (µA) after 5 minutes at 20°C per the series specification.
• Low‑Temperature Impedance — Impedance ratio Z(−25°C)/Z(+20°C) is specified as 8 for the 350–600 V range, providing predictable low‑temperature behavior.
• Dielectric Loss Limit (tan δ) — Series specification lists tan δ (max.) consistent with rated voltage classes (for 160–420 V class, tan δ max 0.15).
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Marking — White printing on a black sleeve for clear part identification.

Typical Applications

• High‑voltage power supplies — Use where 150 µF at 350 V and sustained performance at 105°C are required to support DC bus or smoothing functions.
• Industrial power modules — Suitable for general‑purpose power circuits that require robust ripple handling and long endurance at elevated temperatures.
• Power filtering and energy storage — Designed for applications needing mid‑capacitance energy buffering with defined leakage and loss characteristics.
• Compact chassis installations — The smaller case size (one rank smaller than LGU) and snap‑in mounting make the part useful where board or chassis space is limited.

Unique Advantages

• Long‑term high‑temperature reliability: 3000 hours endurance at 105°C under rated ripple current supports sustained operation in hot environments.
• Defined ripple performance: Published ripple current ratings at 120 Hz and 100 kHz let designers size parts against expected AC stress.
• Compact snap‑in form factor: Radial snap‑in can construction provides a secure mechanical mounting option while reducing occupied volume versus larger case sizes.
• Predictable electrical limits: Leakage current, tan δ, and low‑temperature impedance are specified in the series datasheet for reliable design margins.
• Regulatory compliance: RoHS conformity supports use in products targeting restricted‑substance requirements.
• Clear marking and identification: White on black sleeve marking aids assembly and inventory control.
