HL SERIES

Product catalog summary

Overview
HL series chokes are designed for high current applications, featuring high saturation cores and flame retardant shrink tubing, making them suitable for switching power supply circuits. They offer a low price and a wide selection range from 2.7µH to 100,000µH, supporting up to 15.5A. An option for ER Military Screening is available per MIL-PRF-15305 Grp.A.

Specifications

Test Frequency: 1KHz @0DCA
Tolerance: ±10% standard (options for ±5%, ±15%, and ±20%)
Temperature Rise: 20°C typical at full rated current
Temperature Range: -55°C to +125°C (no load), +100°C max at rated current
Saturation Current: Lowers inductance by approximately 5% (10% max)

Applications
Typical applications include buck/boost converters, noise filtering, DC/DC converters, SCR & triac controls, EMI suppression, switching power circuits, audio equipment, telecom, filters, and power amplifiers. They are designed for use with Linear Tech LT1073 & LT1173, National Semi LM2574, and Unitrode UC2575. Customized models are available.

Inductance and Current Ratings
The document provides detailed tables listing inductance values, DC resistance, saturation current, and rated current for various models in the HL series.

Physical Dimensions
Dimensions for HL7 and HL9 series are provided, with maximum sizes specified in both inches and millimeters.

Additional Information

Tolerance Codes: J= 5%, K=10% (standard), W= 15%, M= 20%
Packaging: Available in Bulk (B) or Tape & Reel (T)
Inductance is denoted by significant digits and a multiplier (e.g., 1R0=1uH, 100=10uH)
Termination options include lead-free (W) and Tin/Lead (Q), with RoHS compliance noted.
