LGY1C273MELB40

The LGY1C273MELB40 is a snap‑in terminal aluminum electrolytic capacitor offering 27,000 µF capacitance at a 16 V rating. Designed for high‑temperature long‑life operation, it supports continuous use up to 105°C with a rated endurance of 5,000 hours at that temperature.

Typical use cases include industrial power supplies and ballast applications where large bulk capacitance, high ripple handling and long operational life are required. The part combines high capacitance density with snap‑in mounting for secure board installation and ease of assembly.

Key Features

• High Capacitance — 27,000 µF bulk capacitance for energy storage and smoothing in power systems.
• Rated Voltage — 16 V nominal voltage suitable for low‑voltage power rails and filtering.
• High Temperature Long Life — Rated for operation from −40°C to +105°C with an endurance of 5,000 hours at 105°C.
• Snap‑in Mounting — Radial, can‑style snap‑in package (φ30 × 40 mm) for secure chassis/PCB installation and reliable mechanical retention.
• Ripple Current Performance — Supports 3,600 mA at 120 Hz (low frequency) and 4,140 mA at 50 kHz (high frequency) to handle heavy AC ripple loads.
• Leakage and Loss Characteristics — Typical leakage current of 1,970 µA and tan δ (DF) up to 0.50 at 20°C, 120 Hz.
• Tolerance and Polarization — ±20% capacitance tolerance; polarized component for correct DC orientation.
• Compliance and Packaging — RoHS‑compliant and supplied in tray packing; product is in mass production.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage in high‑temperature, high‑reliability supply designs.
• Ballast Circuits — Specified as suitable for ballast applications where long life at elevated temperatures is required.
• General Purpose Power Filtering — Large bulk capacitance for DC link smoothing, decoupling and ripple reduction in industrial electronics.

Unique Advantages

• Extended high‑temperature endurance: 5,000 hours at 105°C provides predictable long‑term performance in thermally demanding environments.
• High energy density: 27,000 µF in a φ30 × 40 mm can offers substantial bulk capacitance while keeping board footprint compact.
• Solid ripple handling: Rated ripple currents of 3.6 A (120 Hz) and 4.14 A (50 kHz) reduce heating and improve reliability under heavy AC stress.
• Practical mounting: Snap‑in terminal and radial can package enable secure mechanical retention and straightforward assembly into power modules.
• Verified electrical characteristics: Specified tan δ and measured leakage current (1,970 µA) allow predictable design margining for filtering and hold‑up time calculations.
• Environmentally compliant: RoHS status supports regulatory requirements for commercial and industrial equipment.
