Tadiran HLC-1520 Spec Sheet

Product Overview

The Tadiran HLC‑1520 is a Hybrid Layer Capacitor (HLC) designed to deliver high‑current pulse power in long‑life industrial, military, and IoT devices. When paired with Tadiran’s bobbin‑type LiSOCl₂ primary cells, the HLC‑1520 supplies the short, high‑drain bursts required for RF transmissions, sensor activation, and wireless communication, while preserving the primary cell’s exceptional long‑duration capacity. This architecture supports 10–25+ years of autonomous operation in remote or maintenance‑restricted environments.

High‑Pulse Energy Storage for Ultra‑Long‑Life Systems

The HLC‑1520 acts as a pulse‑power buffer, enabling low‑drain systems to deliver high‑current bursts without stressing the primary battery. Its functional advantages include:

• Delivery of high‑current pulses for RF, sensing, and data transmission

• Stable voltage during heavy load events

• Rapid recharge from the paired LiSOCl₂ cell

• Reduced voltage sag and extended primary cell life

• Optimized performance for devices with long sleep cycles and brief, high‑drain wake cycles

This makes the HLC‑1520 ideal for systems requiring instantaneous activation while maintaining extremely long standby life.

Hybrid Layer Capacitor Technology

Tadiran’s HLC technology combines the characteristics of a capacitor and a rechargeable cell, enabling reliable pulse performance over decades:

• Very low self‑discharge, preserving stored energy for long intervals

• Fast recharge between pulses

• High pulse currents, often in the hundreds of milliamps depending on system design

• Stable voltage plateau during RF or sensor bursts

• Long operational life, matching the lifespan of the primary LiSOCl₂ cell

This hybrid design ensures consistent pulse capability even after years of dormant operation.

Mechanical and Environmental Durability

The HLC‑1520 is engineered for rugged industrial and outdoor environments:

• Hermetically sealed metal housing for leak‑proof operation

• High resistance to shock, vibration, and mechanical stress

• Wide operating temperature range (typically −40°C to +85°C)

• Long‑term reliability in remote or inaccessible installations

Its robust construction supports mission‑critical deployments where maintenance is impractical.

Typical Applications

The HLC‑1520 is widely used in systems requiring long‑life standby power with periodic high‑current demands, including:

• Utility metering (AMR/AMI)

• Industrial IoT sensors and wireless modules

• Asset tracking and geolocation beacons

• Military and aerospace electronics

• Oil & gas instrumentation

• Environmental and structural monitoring

• Smart city infrastructure nodes

• Medical telemetry and diagnostics

These applications rely on the HLC‑1520 to deliver instantaneous pulse power while enabling decade‑long system life.

Why Engineers Choose the HLC‑1520

• High‑pulse capability for RF and sensing bursts

• Ultra‑low self‑discharge for long‑term standby

• Stable voltage under heavy load

• Rapid recharge from LiSOCl₂ primary cells

• Rugged, maintenance‑free design

• Proven reliability in industrial, military, and remote systems

The HLC‑1520 is selected when designers need high‑pulse performance without compromising the long‑life efficiency of a primary lithium power source.
