RC-TFSK4-434

RF Transmitter Overview

The RC-TFSK4-434 is a 433.92MHz FSK radio transmitter module designed for wireless data transmission applications. It operates within a DC voltage range of 2.4 to 3.6 volts and draws a current of 14.5mA during operation. The module delivers an output power of 10dBm at the standard frequency of 433.92MHz. Its physical dimensions are specified as 30.5mm by 10.3mm, featuring a standard pinout configuration for integration into electronic circuits.

RF Transmitter Feature Summary

• Supports Frequency Shift Keying (FSK) modulation for reliable data transmission
• Operates on low voltage DC supply ranging from 2.4V to 3.6V
• Features compact form factor with standard pinout layout

RF Transmitter Applications

• Wireless remote control systems
• IoT sensor node transmission
• Short-range data telemetry

RF Transmitter Procurement Notes

Verify that the specific batch matches the 433.92MHz frequency requirement for your region's ISM band regulations. Confirm the operating voltage aligns with your system's 2.4V to 3.6V supply constraints. Ensure the standard pinout is compatible with your PCB footprint design before finalizing procurement.

RF Transmitter Selection Notes

Select this module when FSK modulation is required for improved noise immunity compared to ASK/OOK alternatives. The 10dBm output power provides adequate range for short-distance applications. Consider the 30.5x10.3mm size constraint against available board space. This model is suitable for battery-powered devices due to its defined current consumption profile.

RF Transmitter Part Context

This component belongs to the RadioControlli RF module series, specifically engineered for UHF band transmission. It serves as a direct replacement or upgrade for legacy ASK modules where signal stability is critical. The standardized pinout facilitates easy migration in existing designs requiring minor form-factor adjustments.

RF Transmitter Replacement Considerations

Direct substitutes include the RC-TFSK3-434, which shares identical electrical specifications but differs in physical dimensions (20.32 x 11.43mm). Verify mechanical clearance when swapping between these two models.
