What are the key features of 3224J-1-502E?
- Sealed construction protecting internal resistance element from dust, flux, and moisture ingress during SMT reflow and field operation
- Horizontal screw actuator allowing flat-access trimming with a standard screwdriver after PCB assembly in low-clearance enclosures
- 5 kOhm resistance value in a surface-mount package enabling compact board-level resistance trimming without through-hole tooling
- Single-turn adjustment mechanism providing straightforward calibration with predictable resistance change per actuator rotation
What is 3224J-1-502E used for?
The Bourns 3224J-1-502E SMD trimmer potentiometer is used for board-level calibration and fine adjustment of analog circuits including voltage reference dividers, gain-setting networks, and offset null circuits in instrumentation and industrial control equipment. Its sealed construction makes it reliable in environments where flux contamination during reflow soldering or airborne particulates in service could otherwise degrade the resistance element. The compact surface-mount footprint is well suited for space-constrained PCBs in medical devices, test equipment, and precision sensor conditioning circuits requiring stable long-term adjustment.

Frequently Asked Questions
What resistance value does the Bourns 3224J-1-502E provide and how is the 502E suffix decoded?
The suffix 502E encodes a 5 kOhm (5000 ohm) resistance value using the standard EIA resistor code where 50 represents the significant digits and 2 indicates the multiplier (x100). This 5 kOhm trimmer is suitable for voltage divider adjustment, offset null, and gain-setting applications in analog signal conditioning circuits.
How does the sealed construction of the 3224J-1-502E protect the trimmer during lead-free SMT reflow assembly?
The sealed body prevents liquid flux and solder particles from penetrating the resistance element during reflow at peak temperatures up to 260°C, which would otherwise cause resistance drift or intermittent contact. This sealing is critical for surface-mount trimmers that undergo wave soldering or aggressive cleaning processes after reflow in production environments.
In which precision analog circuit calibration tasks is the 3224J-1-502E horizontal screw actuator most beneficial?
The horizontal screw actuator provides top-access trimming with a standard 0.5 mm flat-blade screwdriver, making the 3224J-1-502E ideal for post-assembly calibration of zero-offset circuits, reference voltage dividers, and analog amplifier gain networks where the PCB is fully assembled and clearance to adjacent components limits access. The single-turn travel yields fine resolution suitable for precision adjustments within ±5% of nominal value.
What is the typical lead time for the Bourns 3224J-1-502E and how should designers plan for procurement?
The factory lead time for the Bourns 3224J-1-502E is 8 weeks from order placement, which is typical for sealed SMD trimmer potentiometers in specialty resistance values. Designers should plan prototype and production schedules around this lead time and consider ordering buffer stock of at least 10% above build quantity to avoid line stoppages caused by distributor shortages.
