High Current Power Inductors HCM1104 Series

Category: Cooper Industries, Electronics, Inductors

Overview

The High Current Power Inductors HCM1104 Series by COILTRONICS, a COOPER Bussmann company, are halogen-free and lead-free high current power inductors designed for a multitude of applications. They are RoHS compliant, reflecting adherence to strict environmental standards.

Applications

These inductors are suitable for various applications such as Voltage Regulator Modules (VRMs), multi-phase regulators, Point-of-Load modules, desktops, servers, base station equipment, notebook regulators, battery power systems, graphics cards, and data networking and storage systems.

Environmental Conditions

The inductors can operate within a storage temperature range of -55°C to +125°C and can sustain the same range during operation, accounting for ambient temperature plus self-temperature rise. They are also designed to be compatible with J-STD-020D compliant solder reflow temperatures.

Packaging

The HCM1104 Series is supplied in tape and reel packaging to facilitate easy mounting. Each reel contains 850 parts and is 13 inches in diameter, optimized for surface-mount technology (SMT).

Product Features and Specifications

Key features of the HCM1104 series include a maximum total operating temperature of 125°C, a T1.5 x 10.3 x 4.0mm surface mount package size, powder iron core material, and magnetic shielding to reduce electromagnetic interference (EMI). The series boasts a high current carrying capacity with low core losses. The inductance values vary from 0.20uH to 10.0uH, capable of handling current from 7.5 to 45 Amps and operating across a frequency range up to 5MHz.

Detailed Specifications

For in-depth technical information, the datasheet includes a table with product specifications, detailing factors like RMS current (Irms), saturation current (Isat), DC resistance (DCR), and the nominal inductance (L) across different part numbers within the series.

The datasheet also explains the Open Circuit Inductance (OCL) and Full Load Inductance (FLL) test parameters, defined by the frequency, voltage, and DC current conditions under which they are measured. Additionally, it includes information on peak current conditions that cause a specific percentage of roll-off at 25°C. The K-factor, a critical parameter to determine core loss, is outlined for usage in conjunction with other formulae to calculate Bp-p values for the inductor cores.

Part Number Definition

The datasheet provides a breakdown of the part numbering system which is critical for accurately identifying and specifying components. The prefix ‘HCM1104’ denotes the product code and size, followed by an alphanumeric code indicating inductance value in pH, and the suffix ‘-R’ confirming RoHS compliance.

Overall, the HCM1104 Series is presented as a highly reliable and versatile solution for high-current applications that require minimized EMI and compliance with environmental standards.
