LKG1C273MESBAK

The LKG1C273MESBAK is an aluminum electrolytic capacitor in a snap-in (radial, can) package, designed for audio equipment and high-fidelity applications. It delivers very large bulk capacitance (27,000 µF) at a 16 V rating for energy storage and smoothing of power rails in audio systems.

Key electrical and reliability characteristics include a rated ripple current of 3.25 A (120 Hz), a leakage current of 1,970 µA (initial), a tangent of loss angle (tan δ) of 0.45, and an endurance of 1,000 hours at 85 °C. Note: this part is designated End of Life.

Key Features

• Core Type Aluminum electrolytic capacitor optimized for audio equipment, providing large capacitance in a compact radial, snap-in can.
• Capacitance & Tolerance 27,000 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C), enabling substantial energy storage for audio power rails and decoupling.
• Rated Voltage 16 V DC rated voltage suitable for common low-voltage audio amplifier supply rails.
• Ripple Handling Rated ripple current of 3.25 A at 120 Hz, supporting sustained AC ripple filtering in power supply and amplifier applications.
• Leakage & Loss Characteristics Initial leakage current approximately 1,970 µA and tan δ of 0.45 (measured at 120 Hz, 20 °C), specified for predictable low-frequency performance.
• Reliability & Lifetime Endurance specified as 1,000 hours at 85 °C with post-test limits: capacitance change within ±20%, tan δ ≤ 200% of initial specified value, and leakage current at or below initial specified value.
• Package & Mounting Snap-in terminal style (radial, can – snap-in) with dimensions approximately φ30 × 40 mm, provided in tray packing for board-level assembly.
• Operating Temperature Rated for −40 °C to +85 °C, suitable for a wide range of indoor audio equipment environments.
• Compliance RoHS-compliant construction.

Typical Applications

• Professional audio amplifiers — Bulk energy storage and smoothing on low-voltage amplifier supply rails to support transient peaks and maintain steady output.
• High-fidelity home audio systems — Power-supply filtering for improved low-frequency response and reduced audible ripple in playback chains.
• Studio and recording equipment — Stable supply decoupling for preamplifiers and analog signal stages where consistent power delivery supports audio fidelity.

Unique Advantages

• Very large capacitance for compact footprint: 27,000 µF in a φ30 × 40 mm can delivers substantial energy storage where board space is constrained.
• High ripple capability: 3.25 A ripple current rating at 120 Hz supports sustained filtering and reduces stress on upstream regulators.
• Designed for audio use: Series-level design emphasis on high-fidelity audio performance aligns the part with professional and consumer audio applications.
• Clear reliability spec: 1,000-hour endurance at 85 °C with defined post-test limits gives predictable aging behavior for design planning.
• Secure snap-in mounting: Radial snap-in terminals provide robust mechanical retention for board-mounted power components.
• RoHS compliant: Environmentally compliant construction for global product design requirements.
