Frequently asked questions
How do I request samples?
Send your request through the online form or by email, stating the target part number, estimated volume and project stage. We will arrange samples and evaluation boards according to the product stage.
Where can I download product documents?
Non-confidential datasheets can be downloaded from the "Documents" section on each product page. Documents marked confidential require a separate request; we will verify your project before releasing them.
Do you offer pin-to-pin replacements?
Several families are already pin-compatible (current sensors, speed sensors and LDOs). Tell us the part you use today and we will advise on the replacement path.
Do you support custom development?
Yes. RJMICRO can customize products around application requirements, optimizing performance and feature configuration for specific scenarios.
