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% |

JST Hand Crimping Tools
JST WC-491 Hand Crimping Tool for SZH Crimp Terminals
Importance of a High-Quality Crimp
When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage
JST WC-491 Hand Crimping Tool - Overview
From JST a durable, reliable and easy to use hand operated crimping tool made from high quality materials. This crimp tool consists of two ergonomically designed handles with a soft grip for comfortable use, a ratchet mechanism, precision ground die assembly, locator and wire stop. The die assembly has two cavities for wire sizes 26 AWG and 28 AWG. The pre-set load of the tool can be easily adjusted.
Ratchet Mechanism
The ratchet is pre-set to a specific force and remains locked until the handles of the tool are fully closed and the dies are bottomed. The handles cannot be opened until a full crimping cycle is achieved therefore preventing partial crimps. Once the cycle is complete the handles will re-open. The ratchet also enables the operator to repeatedly produce consistent, high-quality crimps. If jamming or terminal misplacement occurs the handles can be easily opened by pushing a ratchet release lever
Locator and Wire Stop
This hand crimp tool features a user friendly flap style locator which ensures the terminal is accurately positioned during the crimping process. The locator is simply flipped open allowing the terminal to be inserted into the correct profile. Once the terminal is inserted the locator is flipped back into place and the crimp tool is closed until the first ratchet. The pre-stripped wire is then inserted into the terminal until it butts against the wire stop, the hand tool can then be closed until the ratchet releases. The locator is opened and the full crimped terminal can then be carefully removed
