SMT Power Inductors Shielded Drum Core PI16ZNL Series Datasheet

Category: Electronics, Inductors, Pulse Electronics Corporation

The datasheet provides technical information on the PI16ZNL series of SMT (Surface-Mount Technology) Power Inductors, which are manufactured by Pulse, a YAGEO company. The given series of inductors features a shielded drum core design tailored for a variety of power applications.

Product Specifications

Key specifications highlight the compact dimensions of these inductors, with a height maximum of 4.8mm and a footprint maximum of 7.8mm x 7.8mm. These components are designed to support a wide inductance range, from 1.8µH to 750µH, and can accommodate varying levels of coupling current, with a rating of up to 3.5A.

Electrical Properties

The electrical characteristics of the PI16ZNL series include an operating temperature range from -40°C to +130°C, an indication of their robustness in diverse environmental conditions. The datasheet lists detailed specifications for individual parts, including Direct Current Resistance (DCR) measured in milliohms, minimum inductance, typical inductance saturation current, and core loss. Each part’s number is associated with its respective inductance value, DCR, and rated currents at various temperature tolerances (-25% and +40°C).

Product Series Variants

The PI16ZNL series includes numerous variants of power inductors, starting from part number P1167.272NL with 2.7µH inductance to P1167.1O5NL offering 1000µH. The datasheet provides a tabular breakdown of each variant’s performance characteristics such as DCR, inductance at zero rated current, minimum saturation current, typical heating current, core loss, and maximum self-resonant frequency (SRF) ranges.

Self-Resonant Frequency

The table outlines the self-resonant frequency (SRF) with values greater than 40MHz for lower inductance parts moving to lower SRF values as the inductance increases, reflecting the performance trade-offs for higher inductance values.

Additionally, the inductance tolerance for specific part numbers is denoted as either ±30% or ±20%, and customers are encouraged to contact Pulse for availability of these components. The datasheet also directs readers to Pulse’s website for further inquiry and provides a document reference (SPM2007_23, dated 02/19) for the datasheet.
