1. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which a failure or malfunction of our Products may cause. The following are examples of safety measures:
2. [a] Installation of protection circuits or other protective devices to improve system safety
3. [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
4. Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM's Products under any special or extraordinary environments or conditions. If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary:
5. [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
6. [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
7. [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2
8. [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
9. [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
10. [f] Sealing or coating our Products with resin or other coating materials
11. [g] Use of our Products without cleaning residue of flux (Exclude cases where no-clean type fluxes is used. However, recommend sufficiently about the residue.); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering
12. [h] Use of the Products in places subject to dew condensation
13. The Products are not subject to radiation-proof design.
14. Please verify and confirm characteristics of the final or mounted products in using the Products.
15. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse , is applied, confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability.
16. De-rate Power Dissipation depending on ambient temperature. When used in sealed area, confirm that it is the use in the range that does not exceed the maximum junction temperature.
17. Confirm that operation temperature is within the specified range described in the product specification.
18. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document.
