LOW PROFILE SELF-LEADED POWER INDUCTORS

Category: Electronics, Inductors, Pulse Electronics Corporation

Executive Summary

This datasheet details the LOW PROFILE SELF-LEADED POWER INDUCTORS designed primarily for PCMCIA (Personal Computer Memory Card International Association) applications by Pulse Engineering, Inc. The components are known for their compact size, specifically 0.38″ x 0.43″ x 0.098″, tailored to meet the stringent space constraints of PCMCIA card designs.

Product Range

The series includes a variety of models denoted by part numbers PO108, PO107, PO106, PO116, PO105, PO104, PO103, PO102, and PO101, including parallel configurations for each. These inductors are engineered to operate within a frequency range of 100 kHz to 1 MHz and can handle up to 3 amps rated DC current. They are designed to be surface mountable and are suitable for pick and place manufacturing processes.

Electrical Specifications

Electrical characteristics are provided at a standard operating temperature of 25°C. The datasheet specifies key parameters such as part numbers, DC current rating, DCR (DC Resistance) max, core inductance at 100 Gauss, and energy storage capacity both at rated current and at 100 Gauss. Control values and calculation data including ET (Energy Product) and permeability are also provided to help engineers assess the inductors’ performance in their specific applications.

Design and Performance Notes

The datasheet notes that the inductance value mentioned is typical when subjected to the rated DC current. It explains how to calculate core loss using frequency and operating flux density (B), temperature rise, and total loss within the inductor. The document further provides instructions on estimating temperature rise within an application by determining copper and core losses. A caution is also mentioned to limit the DC bias (H) to 31 oersteds.

Mechanical Schematic and Packaging

Key mechanical dimensions of the inductors are listed in both inches and millimeters, with a mechanical schematic provided for reference. The weight of an individual inductor is stated to be 0.25 grams. For packaging, the company specifies a standard tape and reel package accommodating 1250 pieces per reel and a tube package with 55 pieces per tube.

Contact Information and Warranty

Contact details for Pulse Engineering offices in the United States, United Kingdom, France, Singapore, Taiwan, and Hong Kong are included, alongside distributor information. The datasheet concludes by stating that the performance warranty is limited to the parameters specified and that data is subject to change without notice. The production date of the datasheet is noted as May 2003 (5/03), on recycled paper, indicating Pulse Engineering’s environmental consideration.

This concise summary extracted from the first two pages of the datasheet ensures a quick comprehension of the main features, specifications, and operational guidelines of the LOW PROFILE SELF-LEADED POWER INDUCTORS, beneficial for designers and engineers in electronics and PCMCIA applications.
