THT/SMT Power Inductors Designed for National’s 260kHz Simple Switcher – YAGEO Company

Category: Electronics, Inductors, Pulse Electronics Corporation

Overview

YAGEO Company presents its lineup of THT/SMT Power Inductors, specifically designed to be compatible with National Semiconductor’s 260kHz Simple Switcher, under the series LM26ZX. These inductors are ideal for various applications requiring high-quality power inductance and are tested and recommended by National Semiconductor.

Key Features

The main attributes of these inductors include:

Compliance with UL94V-0 flammability standards.
Availability in both surface mount (SMT) and through-hole (THT) versions.
The “NL” suffix indicating RoHS-compliant part numbers.
Possible customization with optional Tape & Reel packaging by adding a “T” suffix to the part number, adhering to industry standard EIA481.

Product Specifications

The product series includes a range of inductors with nominal inductance values varying majorly from 10μH to 50μH, nominal rated currents ranging up to 5.0Adc, and Differential Mode Voltage Time (ETop) values up to 40.0V-μsec. However, an important note specifies that inductance values may vary by ±20%.

Operating Conditions

The inductors are designed to operate within a temperature range of -40°C to +130°C, ensuring reliability across a broad spectrum of environmental conditions. It’s also specified that the maximum temperature should include both the ambient temperature and the temperature rise of the component.

Packaging and Part Numbers

Pulse Electronics offers parts in different packages, with THT versions having part numbers like POB4xNL and SMT versions as POB4xSNL, where ‘x’ corresponds to various model numbers. Package types include Through Hole with varying lead diameters and Surface Mount with package codes such as Hcl-68, ICI-44, LCI-50, and Bigfoot.

Environmental Compliance and Customization

The datasheet emphasizes the availability of RoHS compliant variants, denoted by the ‘NL’ suffix in the part number. Non-NL suffixed parts, although not necessarily RoHS compliant, are assured to be electrically and mechanically equivalent to their NL counterparts.

Additional Information

The manufacturer recommends connecting in series, with pins 2-4 connected, to meet specific circuit requirements. For further details, contact information is provided, and potential customers are encouraged to inquire about RoHS compliant versions if their desired part number does not have the ‘NL’ suffix.
