Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Microchip PIC12F 8-bit PIC® Microcontrollers
Microchip’s PIC12F Microcontrollers (MCUs) were the world’s first 8-Pin microcontrollers. Originally launched as One Time Programmable (OTP) parts, this range of devices continues to expand as Microchip adds extra features, further improves specifications and continues to offer ever greater value. Key to the success of the PIC12F was the internal RC oscillator that allowed six I/O channels in an 8-pin package. Later versions of this RC oscillator are configurable between 31kHz and 32MHz.
PIC12F1822/1840 8-Bit Flash Microcontrollers
Microchip’s PIC12 Microcontrollers (MCUs) were the world’s first 8-Pin microcontrollers. Originally launched as One Time Programmable (OTP) parts, this range of devices continues to expand as extra features and further improvements are added.
The PIC12F1822/1840 family of microcontrollers is based upon Microchip’s enhanced mid-range core that features a deep hardware stack and 49 instructions. These MCUs provide up to 8 MIPS, 3.5 Kbytes program memory and data memory of 128 bytes. On board is a configurable RC oscillator with ±1% accuracy.
