1810LP07A0200001T

Overview

The Johanson Technology 1810LP07A0200001T is a surface-mount low-pass RF filter designed for signal conditioning applications. It features a center frequency of 1.81 GHz and a bandwidth of 200 MHz, with an insertion loss of 0.5 dB. The component operates within a temperature range of -40°C to +85°C and utilizes a 0402 (1005 Metric) package measuring 1.00mm x 0.50mm x 0.43mm. It supports a 50-ohm impedance system and is available in tape-and-reel packaging.

Feature Summary

• Provides low-pass filtering characteristics for radio frequency signal conditioning
• Utilizes a compact 0402 surface-mount package for space-constrained designs
• Operates reliably across industrial temperature ranges from -40°C to +85°C

Applications

• Wireless local area network (WLAN) systems
• Bluetooth connectivity modules
• Zigbee communication devices
• IoT sensor networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current part numbering guidelines, as legacy designations may differ from active production codes. Confirm RoHS compliance status directly with the supplier or official datasheet before integration. Ensure the procurement channel sources genuine components to guarantee electrical performance consistency and long-term reliability in final assemblies.

Selection Notes

Select this component when a low-pass filter is required at the 1.81 GHz center frequency with a 200 MHz bandwidth. The 0.5 dB insertion loss makes it suitable for applications requiring minimal signal attenuation in the passband. The 0402 footprint allows for high-density PCB layouts, while the 50-ohm impedance ensures compatibility with standard RF transmission lines and matching networks.

Part Context

This component belongs to Johanson Technology's LP series of low-pass filters. It serves as a modern replacement for legacy part numbers such as 1810LP07A200T. The device is engineered for use in wireless communication standards including Wi-Fi, Bluetooth, and Zigbee, providing essential harmonic suppression and out-of-band noise rejection in compact form factors.

Replacement Considerations

The legacy part number 1810LP07A200T is documented as a predecessor. Verify functional equivalence and pinout compatibility before substitution. Ensure that any alternative components meet the same 0402 package dimensions and 1.81 GHz center frequency specifications.
