Tadiran HLC-1550 Spec Sheet

Product Overview

The Tadiran HLC‑1550 is a high‑pulse hybrid layer capacitor engineered to work alongside Tadiran LiSOCl₂ batteries, delivering the surge currents required by modern industrial, IoT, and metering applications. As long‑life devices increasingly rely on wireless communication and high‑drain events, the HLC‑1550 has become a critical component for ensuring stable, maintenance‑free power over 10–20+ years.

What the HLC‑1550 Is and Why It Matters for Long‑Life Power Systems

The HLC‑1550 is designed to solve a core limitation of bobbin‑type LiSOCl₂ cells: low pulse capability. While primary lithium cells excel at long‑term, low‑drain power delivery, they cannot reliably support high‑current bursts required for RF transmission, GPS pings, or sensor activation. The HLC‑1550 bridges this gap by storing energy and releasing it instantly when needed.

Key performance advantages include:

• High‑current pulse delivery for RF, LoRa, NB‑IoT, and wireless modules

• Stable voltage under load, even after years of inactivity

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

• Rapid recharge from the paired LiSOCl₂ cell

• Long service life aligned with Tadiran TL‑series batteries

This combination makes the HLC‑1550 ideal for devices deployed in remote, sealed, or hard‑to‑access environments.

Hybrid Layer Capacitor Technology and Performance Benefits

The HLC‑1550 uses Tadiran’s proprietary Hybrid Layer Capacitor (HLC) technology, which blends the characteristics of a capacitor and a rechargeable cell. This design provides:

• Strong, repeatable pulse currents for communication bursts

• Consistent voltage response after long dormant periods

• Reliable operation across wide temperature ranges (typically −40°C to +85°C)

• Reduced stress on the primary battery, extending overall system life

For engineers designing long‑life industrial electronics, this hybrid architecture ensures predictable performance throughout the device’s entire operational lifespan.

Common Applications for the Tadiran HLC‑1550

The HLC‑1550 is widely used in industries where long‑term reliability and high‑pulse capability are essential:

• Utility metering (AMR/AMI)

• Industrial IoT sensors and wireless communication modules

• Asset tracking and GPS‑based monitoring

• Military and aerospace electronics

• Medical telemetry and diagnostic devices

• Automotive toll tags and embedded systems

• Agritech and environmental monitoring networks

These applications benefit from the HLC‑1550’s ability to support high‑drain events without compromising the longevity of the primary battery.

Why the HLC‑1550 Is a Preferred Choice for Engineers and OEMs

• High pulse capability for RF and sensor activation

• Ultra‑low self‑discharge for long‑term storage and deployment

• Long operational life matching primary LiSOCl₂ cells

• Wide temperature tolerance for harsh environments

• Maintenance‑free operation for sealed or remote devices

• Proven reliability in global industrial and mission‑critical systems

The HLC‑1550 is often selected for designs requiring 20‑year power, high‑pulse performance, and zero‑maintenance operation, making it a top choice for OEMs building next‑generation industrial electronics.
